BGP IPv4 LU over BGP IPv4 SR-TE Tunnel with IPv4 OSPF

This feature extends the support for the BGP Labeled Unicast (BGP-LU) service for color-based mapping of VPN services over segment routing-traffic engineering (SR-TE) LSPs. Specifically, this feature enables you to advertise BGP-LU IPv4 prefixes with an IPv4 next-hop address. In this case, BGP-LU can resolve IPv4 routes over BGP SR-TE signaled colored SR-TE tunnels established in a network with the OSPF protocol distributing IPv4 segment routing SIDs. BGP-LU constructs a colored protocol next hop, which is resolved on a colored SR-TE tunnel.
